Like [1]} we try to fit the lightcurve of the hydrogen-poor SN 2018don. The lightcurves shapes that best fit the light curves are those of case EXP1 (Fig. REF ). However, these lightcurves evolve too rapidly. We showed that by increasing the mass in the CSM and/or reducing its velocity we can prolong the lightcurve (Fig. REF ). Because of the numerical difficulties we could not obtain lightcurves with similar shapes to that of SN2018do. For that, we simply took the lightcurve from the middle panel of Fig. REF  and stretched the time by a factor of 4. In order to fit the lightcurve of SN2018 we will have to make an extensive search of the parameter space, including changing the properties of the exploding jets and compositions of the CSM and ejecta, something we did not do here.
